I am a first time poster on this site I have been vaping for quite a while but I still have a lot of questions. Anyone have a link to a thread or site that can explain the ohm rating and how using watts or volts effects different tastes or amount of vape in whatever ohm your device is? Also I have an itaste MVP and a zmax and my zmax is constantly screwing up and scrolling through the menu or going up and down in wattage when I'm trying to use it I think I dropped it too many times. But whatever I use iclear30 or evod tank I can't get great airflow on some of them but others do I don't understand why it's different. I have 5 evod tanks and 2 of them have great airflow while 3 do not. I haven't been that impressed with flavors either and have been thinking of getting into a dripping atomizer so any suggestions or sites to learn more about those would be great too thanks for the help
